A vehicle in central London that was packed with explosives, gas canisters and nuts and bolts would have caused “significant damage,” a British security official told The Associated Press Friday.

Authorities said they had defused an explosive device found in the parked car, and the new government called an emergency meeting of senior security chiefs to investigate.

(h/t: Sister Toldjah who notes that, “Pajamas Media has more, including reports that police are now searching landmark sites in London for other explosive devices.”)

Updates when more is known.
